Aptitude and Reasoning, combined together plays an integral part in today's competitive exams. 40 topics and half of the weightage is given to it. Many fear these subject just because they have presumed that they can't do it. Instead of worrying, try to take these as puzzles and enjoy solving problems.

In first column = (36/6)*2 = 12
In second column = (64/8)*2 = 16
Similarly, third column = (100/10)*2 = 20
or you can see it as, first row has square of the number present in the row 2 and row 3 has twice of the number in row 2.
16. Select the related figure from the given alternatives
Ans: (A)
Form question figure, all designs are reversed. Similar rule follows from question figure, each symbol is reversed. Hence, Figure (a) is the appropriate answer.
17. Find the odd figure from the given alternatives.
Ans: (B)
Except figure (b), all other figures two inner shaded designs adjacent to each other.
18. Which one of the answer figures will complete the given question figure?
Ans: (C)
The 4th missing part will have a circle segment. So only (b) or (c) can be true. Closely observing, the circle segment doesn't a line in between. So only (c) is correct.
19. Which one of the given response would be a meaningful order of the following?
1. Lung
2. Nostrils
3. Windpipe
4. Blood
A. 1,2,3,4
B. 2,3,1,4
C. 1,3,4,2
D. 4,3,2,1
Ans: (b) 2,3,1,4
Nostrils = either of two external openings of the nasal cavity in vertebrates that admit air to the lungs and smells to the olfactory nerves.
Windpipe = the air passage from the throat to the lungs.
Lung = each of the pair of organs situated within the ribcage, consisting of elastic sacs with branching passages into which air is drawn, so that oxygen can pass into the blood and carbon dioxide be removed.
Blood = the red liquid that circulates in the arteries and veins of humans and other vertebrate animals, carrying oxygen to and carbon dioxide from the tissues of the body.
Therefore, the meaningful order is Nostrils - Windpipe - Lung - Blood
20. The following graph shows the demand and production of cotton by 5 companies A,B,C,D and E. Study the graph and answer the questions given below.
i) The demand for company B is what percent of the demand for company C?
A. 1.5
B. 2.5
C. 25
D. 30
Ans: (C) 25
Demand of company B = 600 tonnes
Demand of company C = 2400 tonnes
According to question, the required percent = ( demand B)/ (demand C) * 100 = 25%.
ii) What is the ratio of companies having more demand than production to those having more production than demand?
A. 2:3
B. 4:1
C. 3:2
D. 1:4
Ans: (C) 3:2
More demand companies = A,C,F No. of More demand companies = 3
More production companies = B, D no. of more production companies = 2
therefore, the required ratio = 3/2 = 3:2
iii) What is the difference ( in tonnes) between average demand and average production of the five companies taken together?
A. 320
B. 420
C. 2100
D. 1050
Ans: (B) 420
Average demand of five companies = (3000+600+2400+1200+3300)/5 = 2100 tonnes
Average production of five companies = (1500+1800+900+2700+1500)/5 = 16800 tonnes
required difference = 2100 - 1680 = 420 tonnes
